Breeding for tolerance to very low or high temperatures

Breeding for drawfness is good for some crops because:

Resistance to drought, soil salinity, extreme temperatures, heat, wind, cold, and frost.

Elimination of toxic substances is one of the breeding goals for improving cultivar quality. what is the toxic substance being eliminated from cabbage:

A discipline that is useful to plant breeders in utilization which determines market demand for a particular variety

plant breeder produced a new variety of crops for better plant growth habits that exhibit the following except;

A discipline that is useful for understanding breeding for insect resistance

average yield of many crops have increased over time except for;

elimination of toxic substances is one of the breeding goals for improving cultivars quality. what is the toxic substance being eliminated from the seed of cotton:

Is is the place where plants are taken care of before they are finally sold or planted in the field

which is not an advantage of plant nursery management?

It is the process of multiplying the number of species, perpetuating a species or maintaining the youthfulness of a plant.

A discipline that is useful to plant breeding when comparing the performance of many strains.

a discipline that is useful to plant breeders in addressing farmers need or preference

The following are the main undesirable effects of plant breeding on crop improvement except;

these are naturally occurring chemicals produced in one part of the plant and translocation to another part, where they perform physiological functions

the reproductive hormone of plants

First to discover the gametophytic system of self-incompatibility in corm

several heading varieties of lettuce was developed in?

this often specialises in plants that are in demand and can be container grown to save space

plant nurseries are advantageous because

it is the place where plants are taken cared before they are finally sold or planted in the field.

First proposed the dominance hypothesis of heterosis

also known as a wound hormone

he first use the term heterosis in hybrid vigor

developed the world's first transgenic cotton plant in USA

developed the concept of progeny test on individual plants selection on cerials

he developed the concept of pureline

he laid the fundamental laws of genetics by working on garden peas

pollinated date palm as early as 700 B.C.

this technology revolutionized the propagation and mass production of several species especially for ornamentals

proved the existence of a growth substance in oat seedlings and developed the avena test

discovered that light stimulus is found at the tip of the plant

it is the process of bringing a wild species under human management

a form of change in Chromosome number wherein the change was only observed in the whole set of Chromosomes

the following crops exhibit autopolyploidy except

plant breeding is?

the success in plant breeding relies on the available

it is the exchange of segments between homologous chromosomes and powerful mechanism for bringing about variation

the Philippine Rice Research Institute has a Genetic Resources Division that collects and conserves rice genetic resources to ensure the future generations of available seeds needed to build better rice plants in facing climate change and growing population. in other word, philrice has?

the following crops are example of alloploidy in which more than two sets of chromosomes are homologous except

it is the number of individuals with a given genotype divided by the total number of individuals in the population.

familiarization with crop evolution of different species is a prerequisite for plant breeding

it is the only element of evolution that can create new games or alleles

it acts as sieve on genetic recombination

it is the exchange of genetic material between different organisms which leads to production of offspring with combinations of trait that differ from those found in either parents.

a form of change in Chromosome number wherein the change was only observed in part of the Chromosome set

the change in the genetic composition of a population

the ancestor of flowering plants

evolution is a population phenomenon, wherein genetic structure evolves not the population

the following are principles in darwins theory of evolution through natural selection except

the following are alloploid crops having non-homologous set of Chromosome except

plant breeding is directed and accelerated evolution

the type of evolution arising from one species

the Chromosome number of N. tabacum is.

the direct annual ancestors/progenitor of Zea mays ssp mays

the ancestor of rice from wild perennial is

the Chromosome number of emmer wheat is

the evolution of monocoque plants from dicot plants

a type of evolution where two or more species from a similar evolutionary history continue to evolve similar characteristics

a theory of species formation in response to the formation or geographical barries

the independent evolution of analogous structure in unrelated species

the evolution of N. tabacum was done through

the Chromosome number of muscles accuminata

the gradual divergence of species from the population due to genetic polymorphism

there is isolation of individuals in the periphery or border

the Chromosome number of breed wheat

the evolution of wheat was done through

the type of evolution where there is increase in structural complexity and specialisation

the source of genes for disease resistance and higg tillering traits in sugarcane cultivars

which banana variety is an autotriploid
